My invention relates to lasts.

It isthe' object of my invention to provide a hinged last constructionwhich will re sist movement from one position to another but which willpositively stay in either pos1- tion when once moved into the positionde sired.

It'is a'further objectof inyzinvention to provide, alast which will havethe suitable snapacti'on. A i I Referring to the drawings: t

Figure 1 is a side elevation partially in section ofthe last showing thearrangement of the parts within the last and showing by the dotted linesthepositi'on of thelastin collapsed position; and

. F i gure 2 is a section 'ontheline' 2-2 of Figure 1 looking inthedirection ofwthe arrow. v

Referring-to the drawings in detail, 1 is the toe portion of the last, 2the instep and 3 the heel portion. The heel portion carries a transversepin 1 which passes through a cut away portion 5 in the heel transverselythere of at the rear end of the cut away portion 5. Carried on this pin4 within the cut away portion 5 is a link'6. This link carriesintermediate its length transversely thereof a relatively heavytransverse member preferably in the form ofa cylinder designated 7. Theforward end of the link 6 is carried on a transverse pin 8 which is"transverse to the forward end of the cut away portion 9 in thetoe'portion of the last. WVithin this cut away portion the forward endof the link 6 operates. The link 6 is adapted to pivot on the pins 4 and8.

- On either side of the cutaway portion 9 in the toe part of the lastare located open ended cup shaped cylindrical members 9 carrying aplunger 10 therein with an enlarged rounded head 11 fitting within thecylinder 9 with the head normally projecting beyond the edge of thecylinder. The piston or plunger 10 has an enlarged rivet head 12 whichis located on the outside of the face of the cup or cylinder 9* andthereby limits the outward movement of the head 11 of the piston orplunger. The piston or plunger is moved in that direction by the helicalspring 13 which surrounds the piston rod 10, engages the bottom of'thecup on the inside and the underside of the head 11.

a It will be observed that whenthe heel part is moved with the link 6about the pin 8 as a pivot to the transverse'cylinder 7 will en gagewith the head 11 and depress it against the resistance ofthe spring 13.Therefore the heel part will be kept either in the'ex panded orcollapsed position and any movement from oneposition to the other willbe resisted by the helical spring 13, This also provides a suitablesnapactio'n. V q

The: heel is permitted to collapse by reason of the factthat its forwardface is cutaway as at 14- and is normally spaced when in we pandedposit-ion an appreciable distance from the rear face of the toe partwhich is cut away to' form; theface1'5; The toe part extends rearwardlyin a semi-circular portion 16 fitting." into a; semi-circular concavepor tion 17 of the heel part. The cylinder, 7 rolls upon this surfaceof. quadrant form. which 1 surface is designated16; The heelpart andtoepart join each other'on a verticalline 18 for a short distance withinthe bottom of the last, which line 18 intersects with the quadrant line17 at which point a shoulder 19 is forniedupon which the cylinder-7rests.

It will be understood that I desire to-comprehend within my inventionsuch modifications as may be necessary to adapt it to varying conditionsand uses. 7

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. In a last, a toe part, 'a heel part, a projection on the toe part ofquadrant form adapted to engage with cavity of the heel part, a rightangle shoulder on either part adjacent the quadrant projection forforming a limiting shoulder, a link connecting said parts,

means 011 the linkfor engaging with said plunger to resist the movementof the parts from one position to the other and to hold them in eitherof said positions, said projection consisting of a transversecylindrical member carried by said link, said parts having cut awayportions for receiving said link and said transverse member.

2. In a last, a toe part and a heel part adapted to move on one anotherabout a predetermined point, means on said parts for limiting themovement thereof in either direction, a transverse member carried by thelink, and a plurality'of spring pressed plungers carriedby one of saidparts adapted to engage'with said member on the link to a cooperatingcona spring pressed plunger, carried by one of said parts, and

resist the movement from one position to the other of the last parts andto hold them in position when once so moved. i

3. In a last, a toe part and a .heel part adapted" to move on one.another about a predetermined point, means on said parts for limitingthe movement thereof in either direction, a transverse member carried bythe link, and a plurality of spring pressed plungers carried by one ofsaid parts adapted to engage with said member on the link to resist themovement from one position to the other of the last parts and to holdthem in position when once so-moved, said-spring pressed plungers beingmounted in tubular guide Ways havmg means to limit the move- 'ment ofthe plungers in one direction and direction,;a transverse member carriedby the link, a plurality of spring pressedplungers carried by one ofsaid parts adapted to engage With said member on the link to resistthelmovement from one positionto the other of the last parts and toholdthem in position whenonce so moved, said springpressed plungers being.mounted in tubular guide Ways having means to limit the movement of theplungers in one direction and springs to impel the plungers in the otherdirection, the'plungers having heads projecting beyond the guide Waysnoramlly, said plungers being located on either side of said link.

5. In a last, atoe part, a heel part, a link connecting said partslocated in cut away portions therein, a partially circular projection onthetoe part fitting in a concave portion of the heel part, shoulders. onsaid parts for limiting their movement, transverse pins in each ofsaidpart's supporting said link, a'relatively large transversecylindrical member carried by said link,, and a plurality ofreciprocating springpressed plungers mounted on either side of said linkin the toe part in the partially cylindrical projection having headsextendingbeyond the face thereof adapted to be engaged by the relativelylargetransverse member carried by the link, whereby the movement of ithe partsfrom' one position to the other is resisted and When theresistence is overcome the parts are maintained in the predeterminedposition desired;

CLAUSINGn.
